LF4100 12V Lithium Iron Phosphate Battery: Compact 168mm Design with 76.8Wh Capacity

This 12V lithium iron phosphate (LiFePO4) battery, model LF4100, is engineered for users needing a reliable, portable power source with multiple voltage outputs. Its defining characteristic is the combination of a substantial 76.8Wh energy capacity within a compact physical footprint measuring 168mm by 89.2mm by 43mm. Unlike single-output batteries, it provides 12V, 9V, and 5V outputs, making it a versatile choice for powering a range of electronic devices, from small instruments to portable systems. The use of LiFePO4 chemistry contributes to its stated service life of over 2000 charge cycles, offering a balance of capacity, safety, and longevity in a package that weighs approximately 760 grams.

Features and Construction

The LF4100 battery is built around concrete specifications that define its performance and application scope. Its construction prioritises delivering stable power within a defined operating envelope, supported by the included charging accessories.

Material and Build

The core of this power unit is lithium iron phosphate (LiFePO4) battery chemistry, known for its stable discharge characteristics and cycle life. The source text specifies a service life exceeding 2000 cycles, indicating a design focus on longevity. The battery requires a 14.6V input voltage for charging via the supplied 1.5A charger. While the exact casing materials and internal protection circuitry are not detailed, the provided specifications frame it as a self-contained power module ready for integration or use with the included cables.

Size and Practical Fit

With dimensions of 168mm in length, 89.2mm in width, and 43mm in height, this battery is designed for applications where space is a consideration. Its volume is relatively small for its 76.8Wh capacity, allowing it to fit into constrained spaces in vehicles, enclosures, or portable cases. The weight of approximately 760g adds to its portability, making it a candidate for mobile setups or situations where equipment needs to be relocated without requiring a bulky, heavy power source.

Uses and Placement

The multiple voltage outputs and compact form factor of the LF4100 battery open up several practical application scenarios, spanning both occasional and regular use cases.

Event or Professional Use

For professional or event-based applications, this battery can serve as a backup or primary power source for equipment like portable lighting, audio mixers, measurement instruments, or communication devices that operate on 12V, 9V, or 5V. The 5A continuous working current rating means it can support devices with moderate power draw consistently. Its operational temperature range of 0°C to +45°C allows for use in various indoor and sheltered outdoor environments where temperature is controlled.

Everyday Home Use

In domestic or hobbyist settings, the battery is suitable for powering projects, emergency lighting, small electric tools, or as a portable power bank for compatible electronics. The inclusion of DC5521 and DC4017 cables facilitates connection to a range of common DC power jacks. Its rechargeable nature and long cycle life make it a practical alternative to disposable batteries for frequently used devices, provided they match the voltage and current specifications.

Benefits and Buying Value

The value of the LF4100 battery lies in its specified technical attributes, which translate into practical advantages for the user, grounded in the provided data.

Reuse and Low Maintenance

The product's value is enhanced by its rechargeable LiFePO4 design and a service life of 2000+ cycles, which supports extended reuse over many years under normal conditions. This reduces the need for frequent battery replacements. Maintenance is simplified by the dedicated 14.6V charger, and the operating parameters are clearly defined, requiring only that users stay within the temperature and output limits.

Why Choose This Product

This battery is a relevant choice when your primary needs are a compact physical size (168x89.2x43mm), a multi-voltage output capability (12V/9V/5V), and a quantified capacity of 76.8Wh. It stands out for applications where these three factors—size, voltage flexibility, and capacity—must be balanced. The inclusion of a charger and connection cables means it is supplied as a ready-to-use kit, eliminating the need to source compatible accessories separately.
